Mihai Corlan, one of Adobe’s platform evangelists, has written a rather exhaustive introduction to programming in Flex, specifically for current PHP developers.

When I did my first web project using Flex, boy oh boy, it was quite a switch! The clean separation between the client and the server, (the business logic on the client side in addition to business logic on the server side), client-side technology that is compiled instead of interpreted, two languages on the client, all these required a different mind-set from traditional web development. And this is my reason for writing this article. I want to share with you some of the things that are specific to Flex in relation to PHP. At the same time I want to introduce Flex by comparing it with PHP whenever this comparison makes sense.

He goes on to say that the point of this article is not to attempt to convert PHP users over to Flex. But simply that he sees Flex and PHP as choosing the ‘right tool for the job’ for different tasks.

This seems to be a great resource if you’ve been looking at adding Flex to your repertoire as a programmer either for fun or as part of a work project. The fact that it’s written to draw directly on your PHP experience makes it a must read for current PHP folks.
